A conduit run is installed along a ceiling and must be supported every 8-2/3 feet. If the total run is 34-2/3 feet, how many supports are required?
Answer (2)
To support a conduit run of 34-2/3 feet, a total of 5 supports are needed, including supports at both ends. This is calculated by determining how many segments of the distance between supports fit into the total run and adding one more support for the end. The distance between supports is 8-2/3 feet, which translates to 4 segments plus the additional support at the end.

To find out how many supports are required for a conduit run along the ceiling, we need to determine how often the conduit must be supported over its total length. The problem states that the conduit must be supported every 8 3 2 feet. The total length of the conduit run is 34 3 2 feet.
First, let's convert the mixed numbers to improper fractions to make the calculations easier:
8 3 2 = 3 26 This means that each support is placed every 3 26 feet.
34 3 2 = 3 104 This represents the total length of the conduit.
Now, we divide the total length by the support interval to find out how many supports are needed:
Number of supports = Distance between supports Total run = 3 26 3 104 = 3 104 × 26 3 = 26 104 = 4
So, 4 supports are needed. However, we must include one additional support at the starting point of the conduit run.
Therefore, the total number of supports required is 4 + 1 = 5 .
Thus, you will need 5 supports for the conduit run.
